Yeah, go ahead, rub it in. The front plate also reduces your range. At least we don't have as much traffic as you!
In California front plates are required by law. But by my count a bit less than 10% of cars don't use a front plate here. In Santa Barbara I have never had a ticket--except when I have been parked all day in a public garage such as going to our Film Fest or other places meter maids are about. So for the week of Film Fest each year I put on the front plate and take it off afterwards. The only penalty for the ticket is you have to show the police you have put a front plate on and pay a $10 ticket. A small price to pay infrequently to have the car the way I want it!
When we moved to Tucson I was amazed at how easy it was to get from the Northwest side (where I live) to the Southeast side (which is where out SC is). It takes all of 15 min on I-10 and you can actually drive 70 mph the whole way. Not bad in my opinion.
